MAX9632 and MAX9633 Op Amps

Maxim's rail-to-rail operational amplifiers offer high-voltage performance, precision specifications at low frequency, and high gains, enabling precise signal conditioning in industrial applications

Image of Maxim Integrated's MAX9632 and MAX9633 Op Amps The MAX9632/MAX9633 are 36 V, low-noise, precision operational amplifiers with low distortion. The MAX9632/MAX9633 are designed using a proprietary high-speed complementary BiCMOS process (CB5HV). This high-voltage analog process is optimized for excellent AC dynamic performance, ultra-low noise, wide operating voltage range, and low-drift signal conditioning. The MAX9632/MAX9633 target industrial data-acquisition applications that require precision signal conditioning at low frequencies.

The MAX9632 is a single op amp with an ultra-low input-voltage noise density of 0.94 nV/ Hz  , a low offset of 125 µV (max), and an offset temperature coefficient of 0.5 µV/°C (max). The MAX9633 is a dual op amp with an input-voltage noise density of 3 nV/ Hz  , an offset of 200 µV (max), and an offset temperature coefficient of 0.9 µV/°C (max).

Both devices provide high-fidelity signal conditioning with THD specifications better than -136 dB, enabling use in professional audio equipment and high-end test and instrumentation applications. Gain-bandwidth product (GBWP) is typically 55 MHz for the MAX9632 and 27 MHz for the MAX9633. This usable bandwidth, combined with a generous 4.5 V to 36 V operating voltage range and a typical current consumption of 3.9 mA (MAX9632), allows the devices to be used in an array of high-performance industrial applications. Both devices offer a new level of robustness, with up to ±8 kV Human Body Model ESD rating (MAX9632).

Features and Benefits
